Inkjet printer

An inkjet printer, comprising:

• a conveyer comprising a conveyer roller unit, the conveyer roller unit being configured to nip a sheet and convey the sheet along a conveyance direction;
• a recording head configured to discharge ink toward the sheet conveyed by the conveyer;
• a carriage mounting the recording head thereon and configured to move along a scanning direction;
• a corrugation mechanism configured to shape the sheet into a corrugated shape at a corrugating position between the conveyer roller unit and the recording head;
• and
• a controller configured to execute an operation comprising:
• a conveying step, in which the sheet is conveyed by the conveyer;
• and
• a recording step, in which the carriage is moved and the recording head is manipulated to discharge ink toward the sheet,
• wherein the recording step comprises:
• a discharging step, in which the recording head is manipulated to discharge the ink toward the sheet in response to the carriage being placed in a discharging position when a tail end of the sheet is in a position on a downstream side of the conveyer roller unit;
• and
• a corrected discharging step, in which the recording head is manipulated to discharge the ink toward the sheet in response to the carriage being placed in a corrected discharging position, where the corrected discharging position is different from the discharging position, when the tail end of the sheet is in a position between the conveyer roller unit and the corrugating position.

A method comprising steps of:

• conveying the sheet by a conveyer comprising a conveyer roller unit, the conveyer roller unit being configured to nip the sheet and convey the sheet;
• and
• recording by moving a carriage in a scanning direction, and manipulating a recording head mounted on the carriage to discharge ink toward the sheet shaped into a corrugated shape along the scanning direction,
• wherein the step of recording comprises:
• a discharging step, in which the recording head is manipulated to discharge the ink toward the sheet in response to the carriage being placed in a discharging position when the sheet is in a nipped condition, in which the sheet is nipped by the conveyer roller unit;
• and
• a corrected discharging step, in which the recording head is manipulated to discharge the ink toward the sheet in response to the carriage being placed in a corrected discharging position, where the corrected discharging position is different from the discharging position, when the sheet is in a non-nipped condition, in which the sheet is not nipped by the conveyer roller unit.
